「安全不是選項,是基礎。外部密鑰管理系統是 OpenClaw 2026 的安全核心。」
導言:當代理軍團遇上密鑰管理
在 2026 年,我們已經進入了 AI Agent 的時代。Agent 可以自主化執行任務、調用 API、與外部系統交互。但隨之而來的是一個核心挑戰:密鑰安全。
傳統的密鑰管理方式(硬編碼、環境變數、配置文件)已經無法滿足現代 Agent 系統的需求。OpenClaw 2026.3.2 引入了 External Secrets Management,提供了一個完整的密鑰管理工作流。
核心概念:外部密鑰管理
定義
External Secrets Management 是一個專門為 OpenClaw Agent 設計的密鑰管理系統,提供:
- 審計:檢測系統中所有密鑰的配置狀態
- 配置:安全地管理密鑰的配置
- 應用:在運行時安全地應用密鑰
- 重載:無縫更新密鑰而不中斷運行中的 Agent
為什麼需要外部密鑰管理?
| 傳統方式 | 外部密鑰管理 | 優勢 |
|---|---|---|
| 硬編碼在腳本中 | 設定驗證後再應用 | ✅ 防止明文暴露 |
環境變數 (.env) |
Runtime snapshot activation | ✅ 運行時安全 |
配置文件 (config.yml) |
Strict apply target-path validation | ✅ 精確控制 |
| 手動更新 | Safer migration scrubbing | ✅ 遷移安全 |

“Security is not an option, it is a foundation. The external key management system is the security core of OpenClaw 2026.”
Introduction: When the proxy army meets key management
In 2026, we have entered the era of AI Agents. Agents can autonomously perform tasks, call APIs, and interact with external systems. But then comes a core challenge: Key security.
Traditional key management methods (hard coding, environment variables, configuration files) can no longer meet the needs of modern Agent systems. OpenClaw 2026.3.2 introduces External Secrets Management, providing a complete key management workflow.
Core Concept: External Key Management
Definition
External Secrets Management is a secret management system designed specifically for OpenClaw Agent, providing:
- Audit: Detect the configuration status of all keys in the system
- Configuration: Securely manage the configuration of keys
- Apply: Securely apply keys at runtime
- Reload: Seamlessly update keys without interrupting the running Agent
Why is external key management needed?
| Traditional approach | External key management | Advantages |
|---|---|---|
| Hard-coded in the script | Set verification before applying | ✅ Prevent plain text from being exposed |
Environment variables (.env) |
Runtime snapshot activation | ✅ Runtime security |
Configuration file (config.yml) |
Strict apply target-path validation | ✅ Precise control |
| Manual update | Safer migration scrubbing | ✅ Migration security |
Workflow details
